Jason can mow his parents' yard in 3 hr. His brother can mow it in 4 hr. How long would it take them, working together, to mow
the yard? (Assume two mowers are available.)

I would assume it would take 3.5 hours to mow the lawn together.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

y=mx+b is the final answer!   : )
